Answer 1

Explanation

Let us first define the different types of reaction.

A combination reaction is one in which two reactants combine to form a single product.

$2Na+O_2\rightarrow Na_2O_2$

A decomposition reaction will be one in which a reactant breaks down into two or more products.

$2HCl\rightarrow H_2+Cl_2$

A simple displacement reaction will be one in which a reagent, which is in its natural state, displaces one element bound to another. As a product, we will have the previously linked element now in its free form.

$Mg+MnCl_2\rightarrow Mn+MgCl_2$

In a double displacement reaction two linked elements move past each other and take each other's place.

$NaF+KBr\rightarrow NaBr+KF$
